SPATIAL CORRELATION OF QUANTUM-DOT ELECTRONS IN A MAGNETIC-FIELD

For an exactly solvable model the electronic structure and spatial pro bability distribution of a two-dimensional parabolic quantum dot with two interacting electrons in a magnetic field is calculated. As a cons equence of the interplay between electron-electron interaction and mag netic field it is shown that electron spatial correlation presents a d iscontinuous variation as a function of the cyclotron to harmonic freq uency ratio. Physical consequences of this fact are analysed.
